PRICE-COMPUTING BALANCE TRiP-SCALE.

SPECIFICATION forming part of Letters Patent No. 673,095, dated. April 30, 1901.

Application filed September 22, 1900. Serial No, 30,844. (No model.)

To @ZZ whom t may concern:

Be it known that I, EUGENE THORNE, a citizen of the United States,and a resident of Henderson, in the county of Vance and State of North Carolina, have invented certain new and usefulIinprovementsin Price-Oomputing Balance Trip-Scales, of which the following is a specification.

My invention relates to new and useful improvements in balance trip-scales such as are employed for counter service, in which various commodities are weighed, and more especially to a combined price-computing device therefor.

It is the object of my invent-ion to produce a balance trip-scale with a price-computing attachment in a specially-desirable compact and unique manner, whereby quantities of merchandise or other articles maybe weighed and their value in dollars and cen ts computed at a given price, thus greatly lessening the labor in connection therewith.

A further and essential feature of my invention is to provide for said scale, in addition to the computing mechanism,what I term a tally-beam,w hereby desired quantities or values of commodities may be readily weighed out at specified prices, as will later be more fully explained. v

Vith the above and other minor objects in view my invention resides and consists in the novel construction and combination of parts illustrated upon the accompanying two sheets of drawings, forming a part of this specification, upon which similar characters of reference denote like or corresponding parts throughout the several iigureS, and of which- Figure l shows a front elevation of a balance-scale provided with my improved computing device, Fig. 2 is a similar elevation, the position of the computing-dial, weights, dite., being changed. Fig. 3 isavertical crosssection on line a: ce of Fig. 2, illustrating the supports for the dial.

Referring in detail to the characters of reference marked upon the drawings, A indicates the base, B the central pedestal forming the pivot for the beam, C and D supporting end pedestals for the movable ends of the scale-frame, and E represents the balance or scale frame, which may be of the usual or an y preferred construction.

E is a narrow graduated extension of E, forininga tally-beam havinga slidable weight G, the purpose of which construction will again be referred to and described.

II and I represent guided supports connecting` the pedestals O and D with thelbalancing-frame, respectively.

J is a platform attached to the support I, and K is a scoop, of any usual or preferred construction, for use upon said platform.

Upon the balancing-frame of the scale is formed a post L, which I provide with a longitudinal way M to form a guide for a rackbar N,which is slidably mounted therein, said bar being preferably inserted from the top and retained in position by caps O O, secured to the post by means of screws. To either end of the rack-bar N is a weight P, which when adjusted to the extreme right causes the empty scale to balance, and by adjusting said bar to the left I am enabled to tip the scale and counteract the weight of the conimodity which may be placed in the receptacle K, as shown in Fig. 2.

To the post L is secured an extension Q, forming a bearing for the front end of the pivotal shaft R of the dial S, the opposite end of this shaft being supported in a rear post U. (See Fig. 3.) Upon said shaft is also secured a small pinion T, the teeth of which mesh with those of the rack N in a manner to cause the rotation of the pinion by the movement of the rack-bar and likewise a rotary movement of the dial which is connected therewith through the medium of the shaft before mentioned.

The dial S may be divided to indicate as many pounds as desired. In the drawings, for convenience of illustration, I have divided it into eight equal parts Vha. I further divide the dial into a series of circles b, of which in practice there may be any desired number, there being seven represented in the drawings. The spaces between each of these circles are divided into a number of equal parts ranging from twenty-four to sixty, and upon each of said spaces is represented a numeral. The outermost circle of spaces has numerals from l to 56, iiicliisive,\vhile the smaller and innermost circles has numerals from l to 24E. In the operation of my scale these numerals indicate the values in cents of the com- IOO modity weighed at a given price. In front of the face of the upper portion of the dial is represented a stationary indicator @,which is supported from the rear by the post U. This indicator is provided with price-numerals foreach circle or series of gures,which price-n u merals range in the drawings from three to seven cents and are located, of course, directly opposite to the one of the series of numbers to which they apply.

In the operation of my scale it will therefore be noted that the carrying out of my multiple price is as follows: Assuming that the scoop is laden with goods to the weight of six pounds, the adjustable bar and its weight are shifted to the left, (see Fig. 2,) which rotates the dial to the right, thus carrying the entire series of numerals around until the six-pound line registers with the right-hand edge of the stationary indicator c, thus indicating that the weight of the article is six pounds. Presuming, then, that the price of the article is seven cents per pound, it will be simply necessary to look at the dial adjacent to the n umeral 7, where the Afigures 42 will be shown,thus informing you that the six pounds at seven cents amounts to forty-two cents. The same reckoning may be carried out to the full capacity ofthe scale,and,as before stated, the dial may be enlarged, so as to give a larger range of prices, if desired.

A further feature of my scale resides in the tally-beam F, by means of which I am enabled to more readily reckon or weigh up a dollars worth of goods at a stated price per pound. This is accomplished by means of the graduations d upon the beam, which, as will be seen, are represented by price-numerals ranging from 3 to 8,including onehalf cents each. It will further be obvious that the number of those graduations may be increased, if desired. In carrying out this computation of prices it is necessary to have the Weight G of a proper size with relation to the graduations upon the beam to represent a certain amount in Value, and for convenience of description we will presume that said weight represents twenty cents worth. Therefore if it is desired to give a purchaser twenty cents Worth of sugar and the same is selling at iive cents perpound the weight G would be shifted from the position shown in Fig. 1 to the numeral 5 or position shown in Fig. 2, whereupon the commodity would be placed in the scale until the same is balanced, which would indicate twenty cent-s worth at five cents per pound. It' the amount desired to be weighed out is greater than twenty cents worth, the

extra amount is secured by placing upon the depending support fof the weight G one of the detachable weights f, of which there may be any desired number, representing from twenty to eighty cents each. By this means I am able to give a dollars worth or less at from three to eight cents per pound. Thus if you desire a dollars worth at tive cents per pound you would place upon the hanger e an eighty-cent wcightf, which weight, with the original weight e, when adjusted to the pricenumeral (Z desired would give you the dollars worth at the selling-price to which it had been moved. Any less amount can be secured in the same manner by simply applying the proper weightf to the hanger e corresponding to the amount of the value desired to balance.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
